You are presented with a quote, all blanks, with a jumble of letters beneath the blanks. Each letter stands for another letter, and it is up to you to de-code it.
By starting with a short word, you can begin to puzzle your way through the code. When you get a letter correct, it will appear all throughout the quote. You can see here on this screen shot that I filled in “AND” and as I did, the “a” the “n” and the “d” all appeared properly throughout the quote, giving clues for solutions to other words.
